Investigators say Flavia Baustista, 19, disappeared after a domestic disturbance between her and her 25-year-old boyfriend, Francisco Mayoral-Bautista (no relation).
Bautista was last seen at 6:30 a.m. Monday at a friend's house in the 500 block of South West Boulevard.
When her friends returned home from work at 4:00 p.m., police say they found a broken window with drops of blood on it. Police say there was also blood inside the living room, leading to the back door of the house.
Investigators believe Bautista did not leave the home voluntarily.
One neighbor said she is worried for Bautista's safety.
"She sometimes came here to use the phone and she came with bruises," said Ramona Vargas, who said those bruises were from her boyfriend.
Vineland Police say they were called to the same house the previous night for a domestic disturbance.
Police have issued an arrest warrant for Francisco Mayoral-Bautista on assault charges. As for Bautista's disapperance, police said he is a 'person of interest.'
"We'd like to speak to him but, really, we'd like to make sure she is okay. If we find her and she's okay, maybe she can explain the whole thing and everything can come to light," said Detective Sgt. Christopher Brunetta of the Vineland Police Department.
Mayoral-Bautista may be driving a black 2-door Hyundai Tiburon with North Carolina plates.
